如何在没有index.idx文件的情况下附加SQL Server 2008 R2中的数据库

Question

I have a database test ( test.mdf , test_ldf.log and test_idx.idx ). By mistake I deleted the test_idx.idx file and due to file was over 20 GB.

I have used all type of recovery software but can't find the file.

Unfortunately that database is not backed up, and now SQL Server 2008 R2 doesn't let me attach the database.

Is there any way to attach the database test.mdf file without index file?

Error when I try to attach database:

Unable to open the physical file ".idx". Operating system error 2: "2(failed to retrieve text for this error. Reason: 15105)". (Microsoft SQL Server, Error: 5120)

Answer 1

1. create a dummy database (name is not important) with the same file structures. ie a data file, log file and index file.

2. take the index file and database offline like so:

   alter database <dbname> modify file(name = '<name of your index file>', offline)

   alter database <dbname> set offline

You'll not be able to recover the offline file (to my knowledge) so dont give it the same logical name as your original file - you'll see why in a moment.

3. now overwrite the dummy database files with what you have left of your broken database (obviously keep the copies somewhere safe!)

4. bring the database back online

   alter database <dbname> set online

At this point your data should be accessible.

5. create new filegroup/file with the same logical names as your original and rebuild indexes

Good Luck!
